Welcome to Math-Center.Org’s Rational and Irrational Numbers page! This section explores two important categories of numbers that help students deepen their understanding of the number system. In middle school, learners are introduced to rational numbers—numbers that can be written as a fraction or ratio of two integers, including decimals that terminate or repeat. As they progress, students encounter irrational numbers, which cannot be expressed as exact fractions—like √2 or π—and learn how these fit within the real number system. Mastering these concepts is essential for building confidence in algebra, geometry, and higher-level math. Rational and irrational numbers also appear in science, finance, and technology, making them valuable beyond the classroom. This page offers explanations and practice aligned with curriculum standards to help students distinguish, compare, and work fluently with all types of real numbers
